ever, the fish skin employed ism e p treats:

cal-shaped corrugations, withthe'" practically vertical, so thatitsmethod of use maynbe compared with that .of sandpaper. ;In ;oth erwords, the-Taction...of.a fish-skin .=.-with itsconical corrugations?ofthe type used for. cabinetemaking; comes from an up and-down rubh' nmotion on the material .to be 1 1, 11; to ether.

The object of the invention is" a" tool for the rubbing away of the comeof the feet and other similar calluses, that while showing a workingsurface formed-by does .not act byrai i up and down rubbing motiorij'which would be likely to set up inflammation, similar to what might bedeveloped by a rasp or file rubbed over corns or other calluses thathave to'be removed.

The device according to the invention is characterised by the fact thatit is made up of a body piece, roughly in the shape of a spatula,provided with a handle, with at least one of the surfaces of the bodypiece acting as a background for a sheet of fish-skin of which theroughnesses or corrugations are all headed in one and the samedirection.

According-to another feature of the invention, use is made preferably ofthe fish-skin coming from the species Scymnus nicaensz's.

For the making of this particular instrument, and in accordance with theinvention, after the fish-skin to be used is taken off the fish acutting tool is employed to thin it down, then strips are stamped outfrom the portions provided with the right kind of roughnesses, in sizescorresponding to those of the surface that has to take them; these samestrips are then soaked in a bath containing formaldehyde, and then theyare stuck on after drying.

Other characteristics and advantages will make their appearance in thefollowing specification given out with reference to the accompanyingdrawings that are more examples and in which:

Fig. 1 is a plan view of the corn-eradicator.

Fig. 2 is a section along line IIII of Fig. 1.

Fig. 3 is a view similar to that of Fig. 2, showing a modified form ofexecution.

'Usernay bema'de of any fish-skin provided that'the projections having tlie snapeore tootn ora'ourved hook or scales-'4 (see Fig. 4-) that appear onitsouter surfaces areall ben't back and headed in the-saline .directionzxAnfongrt-he fishes with a skin that fulfillsi-the requirements soughtfor nthat' is,- as pointedi out: izprevi'ously, the eradication ofcorals ion .the. feet and other similar.icallositiea-adnay :be;specially mentioned a small dogfish classified as Scymnus m'caensis bythe Naturalist Risso and that is known commonly as gatte, one of theshark family called also Gotta causz'mera, also as liche depending onwhether this fish is caught in the Atlantic or in the Mediterranean.

The corn-eradicator, that is to say the body piece I and the handle 2 ismade up in any suitable way, according to the type of material of whichit is made and for the preparation of the plate 3 and its fastening onthe body I, the following procedure or a similar one may be carried out:

The skin is removed from the fish and a start is made by paring it downby a cutting tool, so that its thickness is substantially eventhroughout; when this is done, those portions. of the thinned down skinare stamped out that exhibit a suitable type of roughnesses, that is tosay where, all the spines or roughnesses are oriented or headed in thesame direction, sloping in reference to the Vertical, so as to formplates 3 corresponding in shape and size to those of the convex surfaceof the body I.

The stamped out plates 3 are then allowed to soak in a formaldehydebath. After drying, each plate 3 is stuck under pressure on the convexsurface of a body I; the edges of this plate that, after gluing, projectover the sides of the body are removed finally by trimming.

The stamping is carried out, preferably, so that after gluing thetooth-like or hook-like projections or scales 4 of the fish-skin areheaded towards the handle 2.

O the con Through being soaked in a formaldehyde bath the plates 3 aremade not only much harder which gives them a longer lease of life, butare rendered aseptic.

To make use of the tool as featured, all that has to be done is to moveit, while pressing lightly, in contact with the corn or other callus toremove it. The plate 3 only does active work when the movement of thetool is from the handle towards the point and consequence is that thehard portions of the corn or other callus are scraped oif in the form ofextremely small particles, without giving rise to any inflammation.

The support or body member depicted in Fig. 3 is formed with two convexsurfaces for the reception of two sections of Scumnus m'caensis skin,which sections may have similar or differentabrading characteristics,depending upon the size and density 01' theirltooth-like spines.

What I claim is: v I

1. A tool for removing ,chiropodic growths, comprising an oblong. memberhaving a convex side face; a handle rigidly connected to said member andhaving an axis arranged parallel to the longer side of said oblongmember; an element of the skin of Scymnus nicwensis secured to saidconvex side face; and projections arranged on said element and eachhaving the shape of a curved hook, said projections being directedtoward said handle. I

2. An implement for removing chiropodic growths comprising a support anda layer oi. Scymnus nicaensis skin secured to said support exposing aplurality of curved tooth-like spines oriented in substantially the samedirection.

,, 3. An implement for removing. chiropodic growths comprising a supporthaving a convex surface and a layerof Scymnus nicaensis skin secured tosaid surface exposing a plurality of plurality of curved tooth-likespln'es oriented in substantially the same direction towards said handleportion.

5. An abrading implement comprising a section of forrrlaldehyde hardenedScymnus nicaensis skin having a plurality of exposed curved toothlikespines oriented in substantially the same direction.

6. An implement for removing chiropodic growths comprising a support anda layer of formaldehyde hardened Scymnus nicaensis skin secured to saidsupport exposing a plurality of curved tooth-like spines oriented insubstantially the same direction. ii a '7. A process of making anabrading implement comprising removing skin from Scymnus nicaensis andtreating said skin with formaldehyde. 1 CHARLOTTE EXIBARD.
